springboot项目中如何实现邮件告警功能(监控平台服务模拟)

介绍

模拟服务器故障，然后实现邮件告警

一、首先配置邮件的maven依赖

代码如下：

<!--邮件告警-->
        <!-- Spring Boot的邮件发送依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>
        <dependency>
            <groupId>com.sun.mail</groupId>
            <artifactId>javax.mail</artifactId>
            <version>1.6.2</version>
        </dependency>

二、其次在ideal中创建相关类文件

2.1、创建一个服务类MonitoringService

使用Spring的JavaMailSender来发送邮件。

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;



/**
 * Created by 姜水桦 on 2024/3/21 16:58
 * 功能描述:
 *         创建一个服务类，使用Spring的JavaMailSender来发送邮件。
 */
@Service
public class MonitoringService {

    private final JavaMailSender mailSender;

    public MonitoringService(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }

    public void sendAlertEmail(String from,String to, String subject, String text) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(text);
        mailSender.send(message);
    }
}

2.2、定义一个监控类

        在你的监控组件中，当检测到异常时，调用EmailService的sendAlertEmail方法来发送邮件。

package com.example.service;

import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;



/**
 * Created by 姜水桦 on 2024/3/21 16:58
 * 功能描述:
 *         创建一个服务类，使用Spring的JavaMailSender来发送邮件。
 */
@Service
public class MonitoringService {

    private final JavaMailSender mailSender;

    public MonitoringService(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }

    public void sendAlertEmail(String from,String to, String subject, String text) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(text);
        mailSender.send(message);
    }
}

2.3、再创建一个控制器类(逻辑层)

EmailController

package com.example.controller;

import com.example.common.AuthAccess;
import com.example.utils.ServiceMonitor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by 姜水桦 on 2024/3/21 19:53
 * 功能描述:
 */
@RestController
public class EmailController {
    @Autowired
    private ServiceMonitor serviceMonitor;

    // 每隔30秒执行一次checkServiceStatus方法
//    @Scheduled(fixedRate = 30000)
//    @Scheduled(fixedRate = 1000)
    @GetMapping("/mail")
    @AuthAccess
    public void monitorService() {
        serviceMonitor.checkServiceStatus();
    }
}

2.4、配置application.yml

spring:
  #邮箱配置
  mail:
    host: smtp.qq.com
    port: 465
    # 使用自己的发送方用户名 + 授权码填充
    username: jiangshuihua1018@qq.com
    password: vyqsovsepomlecdd
    default-encoding: UTF-8
    properties:
      mail:
        smtp:
          ssl:
            enable: false
            required: false
          socketFactory:
            class: javax.net.ssl.SSLSocketFactory
          allow8bitmime: true
        debug: true

注意：这里的密码指的是你QQ账号里面的授权码
